迷迭香酸（罗丹酚酸）对H2O2处理过的皮肤黑色素瘤细胞的抗氧化作用Sun Mi Yoo1 and Jeong Ran Kang2*1.韩国光州500-741号东冈大学美容系2.韩国首尔143-701号建国大学生物工程系2009.2.6收到 2009.4.17接收本学科旨在检测迷迭香酸对人工孵育的皮肤黑色素瘤细胞在ROS下的抗氧化作用。

通过XTT比色法，以细胞毒性和抗氧化作用来分析细胞粘附活性，DPPH自由基清除活性以及H2O2处理1-10h和未经处理的两种情况下乳酸脱氢酶的活性。

用20-110 μM 的H2O2处理皮肤黑色素瘤细胞5-7h后，细胞活性的降低呈剂量和时间依赖性。

通过XTT比色法测得H2O2的半抑制浓度（IC50 ）为90μM。

同时H2O2增强了LDH细胞的剂量依赖性。

用50-90μM的H2O2处理8h后测得LDH50为60 μM H2O2。

迷迭香酸能增强细胞活性和DPPH自由基清除活性，降低乳酸盐脱氢酶的活性。

细胞的H2O2处理证实了对人工孵育的皮肤黑色素瘤细胞的强抗氧化作用。

通过H2O2的处理，迷迭香酸能在细胞内能增强细胞活性和DPPH 自由基清除活性，降低乳酸盐脱氢酶的活性。

这被认为是迷迭香酸对ROS（ROS）如H2O2的抗氧化作用。

Key words：DPPH-radical scavenging, LDH, rosmarinic acid, XTT assay关键字：DPPH自由基清除活性，乳酸脱氢酶，迷迭香酸，XTT比色法据研究发现，ROS通过氧化应激对细胞的损伤和一些脑部疾病比如帕金森症或心脏疾病例如心肌梗塞之间有很大的关联[Difazio et al., 1992; Delanty and Dichter, 1998].尤其是研究人员认为ROS是皮肤老化的一个主要的因素后，一直试图从ROS方面研究衰老。

[Yokozawa et al., 1998].据研究表明，ROS的氧化应激会通过萎缩细胞引起各种疾病，例如超氧自由基、H2O2（H2O2）或羟基自由基的巯基蛋白反应中断酶的活性，破坏脱氧RMA（DNA）或RMA（RNA），诱导细胞膜脂质过氧化。
